This time I discovered that making a syrup is easy. You then add this syrup to cold and carbonated water: instant Mate soda!

I decided to take a sidestep from making Hack42-Mate. I wondered if it would be possible to make an alcoholic version of my Mate recipe. The most natural way seemed to be a mead. The recipe was based on mead recipes I found [http://users.soe.ucsc.edu/~karplus/mead-recipe.html here] and on the two best Mate recipes (3 & 6) from the First Iteration.

::;Notes

+

−

::[[Gebruiker:Lurwah|Lurwah]]: Full taste of honey, without the sweetness of sugar. Notes of Mate come through quite well balanced with the smell and taste of the honey. Takes some getting used to, but very drinkable. Not headache material.

+

−

::[[Gebruiker:WitchDoc|WitchDoc]]: Had a few glasses and liked it very much. Although i'm not sure if it can be contributed to the Mate in the mead i had a hard time getting to sleep that night.

Hack42-Mate

My goal is to develop a recipe for an enjoyable Mate-based soda. If eventually found to be good (enough), we might decide to drink our own Mate instead of buying Club-Mate. Whether we do this or not, it is always possible to brew a batch for a party or large event. Who would say no to a keg of home-brew Mate?

First Iteration

In this iteration I tried to find out a basic recipe that works, or points towards the right direction.
I brewed six different bottles of Mate-soda, based on recipes I found. The plan was to make three basic recipes twice and brew the Mate for either five or seven minutes, resulting in six different batches. The three basic methods were:

This last method is based on the traditional preparation of yerba mate tea.
All recipes were cooled to serving temperature and then carbonated with a SodaClub machine.
I gathered a taste panel during one of our meets for a "blind" (they didn't know the recipes) tasting of the several batches I brewed. Of course, I also gave them a glass of the original Club-Mate (some people didn't like Club-Mate as much as Club-Mate...). They kindly gave their feedback, a summary of which can be found below the recipes.

Recipes

Note: All degrees(°) are in centigrade.

Version 1.

1 liter water (90°)

1 gram citric acid (dissolved)

70 grams sugar (dissolved)

20 grams Mate (brew for five minutes)

(Note: Resulted in rapid expulsion of copious amounts of foam after adding CO2)

The Dutch results are here. (Summary: Version 3&6 were most popular)
I have not yet seen anybody use the recipes in version 3 & 6 to make a Mate-soda. So for me it was an exciting result, that these turned out to be the better tasting ones. I decided after the tasting to work on these two recipes in the future.
